SmartSolo IGU-16HR 3C contains an electromagnetic conversion system that generates millivolt signals proportional to the vibration intensity of the measured medium (usually soil).Three channel moving coil sensor with orthogonal configuration is built in to restore multi direction seismic signal without distortion.The sensor is rigidly connected with the ground through the metal tail vertebrae. The vibration of the earthquake drives the internal coil of the sensor to move around the magnet, and the magnetoelectric conversion occurs, and the coil generates the induced electromotive force;We provide GPS clock signal to ensure the real and effective value of each sample point. The temperature sensor can accurately measure the temperature and correct the error caused by temperature, so as to achieve the pursuit of high-precision data quality.
